Mission District Supervisor David Campos is filing for re-election tomorrow at City Hall.

“I am proud of the work I have accomplished over the last four years,” Campos said in a prepared statement. “District 9 is one of the most culturally diverse areas of our city. I am honored to represent the District and look forward to earning a second term this November 6th.”

Some district residents are expected to join Campos as he officially files for re-election tomorrow at noon at the Department of Elections at City Hall.

Benjamin Castaneda, 23, of 24th Street, so far appears to be the only challenger, the SF Appeal notes.

“I’m fortunate to say that at the age of 23. That this time next year I will be announcing my campaign for Supervisor,” he wrote on his Facebook page in September. “Sorry, David you know I love you but I grew up here too.”

The last time Castaneda’s name was in the news was in 2008, when a San Francisco Chronicle article quoted him as supporting the gang injunction in the Mission “if that’s what it’s going to take to stop innocent people from dying.”

From the Chronicle:

Castaneda’s childhood friend, Noel Espinoza, 19, was killed along with another man Sept. 4 at the edge of the injunction zone. Police said the attack may have been retaliation for the slaying of a man aligned with Sureños.

Castaneda said he believed the victims were not active gang members but had been targeted by rivals of the Norteños because they were on Norteño turf — a scenario that police say is common.

“It’s ridiculous,” Castaneda said. “Why would you kill over red and blue?”
